Application filed May 22, 1916.

1 b all whom it may concern Be it known that I, LELAND L. Foss, a citizen of the United States, resident of Vidalia, in the county of Toombs and State of Georgia, have made a certain new and useful Invention in C0tt0l1G'inS; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is an end view of the invention,

Fig. 2 is a central vertical section of the same. Fig. 3 is a detail perspective view of a hacker frame and connections. Fig. 4 is a similar view showing a modified crank leg. Fig. 5 is a side View of a cotton gin showing further modifications of the crank leg. Fig. 6 is a detail perspective view of the stay bar.

The'invention has relation to cotton gins of the double roller type, designed for operation upon long fiber or sea island cotton, having for its object to provide an improved construction of the hacker frames and of the crank legs of the operating mechanism for said frames.

Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanyingdrawings, illustrating the invention, the numeral 2 designates the main frame of the machine, having end uprights 3; 4 designates the ginning rollers, one at each side of the machine; 5 the breasts, located respectively above therollers and carrying the ginning blades 6, cooperating with the rollers and with the hacker blades hereinafter referred to; 7 the shed boards, inclined respectively toward the rollers, to feed the cotton thereto; 8 the seed griddles projecting toward the rollers, and 10 the hacker blades forming the side bars of vibratory hacker frames 12, and 13 are the reciprocatory feeders, mounted and sliding upon the griddles toward and away from the rollers.

The power or crank shaft is shown at 14, an endless belt 15 engaging pulley 14 upon said shaft and passing upwardly and obliquely around the inner side of the driv- Specification of Letters Patent.

ing pulley 16 for one ginning roller, thence engaging pulley 17 movable to adjust the tension of the belt as hereinafter described, the belt passing next downwardly and engaging the driving pulley 16 for the other ginning roller, and thence to the pulley 14. A driving belt 19 for the feeder shaft engages a pulley 20 upon the shaft of one of the ginning rollers, passing thence to a pulley 21 upon the feeder shaft, a device 22 for adjusting the tension being provided for this belt.

The breasts pass at their ends through perforations or slots of the end frames, and have outer downturned lugs 23, said breasts being suspended from vertical bolts 24, axially adjustable to vertically adjust the breasts, within horizontal slots or flanges 25 of the end uprights, nuts 26 upon said bolts providing for this adjustment. The breasts are also horizontally adjustable through adjustment of upper and lower horizontal bolts 27, 27, said bolts at their ends pivotallyengaging the stems of upper and lower bolts 28, 28, carried by the breasts, the lower bolts 27 at their outer ends engaging vertical slots 28 of fianges 30 of the end uprights, and the upper bolts 27 being connectedrespectively by turnbuckles 29, the adjustment of said upper and lower horizontal bolts being efl'ected by means of the nuts 29 thereon and of the turnbuckles 29, said nuts bearing against said flanges. Upon suitable differential adjustment of the horizontal bolts, together with adjustment of the vertical bolts 24, the breasts may be obliquely adjusted to one side or the other, in an arcuate path, to give an oblique or leaning adjustment to the ginning blades with respect to the rollers, the blades moving from their tangential lines of contact with said rollers as centers. Upon suitable adjustment of the horizontal and vertical bolts the breasts may be adjusted toward or away from each other, or they may be adjusted vertically.

Coiled springs 40 surround the bolts 24, said springs bearing at their upper ends against the flanges 25, and at their lower ends bearing against the breasts, through the medium of nuts 41 and washers 41 upon the nuts, whereby the breasts may move upwardly in a yieldable manner against the tension of the springs, in case of strain upon the ginning blades brought about usually by wads of lint, in the upward movement of the hacker blades. The tension of the springs is varied by adj ustment of the nuts 41. In this way, the tension of the springs of each breast may be adjusted independently and made greater or less for one breast than for the other, as is required in some cases.

' Each hacker frame 12, including the central shaft 12, the oppositely extending arms 12 and the hacker blades 10 at the outer ends of said arms, is preferably made in one integral casting, and each V-form frame 30, depending from the hacker frame and connected to the crank of the power shaft by crank leg 88, is also made in one 7 l5 blade. 5

In "Fig. 4 of the drawings a modification of the V-form frame is shown, havingfour upwardly extending branches 30 instead of two as in the first form of said frame, and

inFig. 5 a further modification is shown wherein two of these diverging branches arelocated 1n a vertlcal plane and the other two located in an inclined plane, this form ,of the device being suitable for use at the ends of the machine to avoid, in certain cases, necessity for intermediate supports for-the crank shaft.

By making the hacker frame, including the shaft, the oppositely extending arms and the blades, in one integral part, andlthe V-form frame 30 in another single integral part, many extra parts shown in my Patent No..730,4 49, dated June 9, 1903, are dis pensed with, and the construction and the connections much simplified, rendering the device more easily assembled and lessening the parts liable to workloose.

' The crank shaft is supported in bearings 'ofthe end frames, and in order to provide intermediate supports for this shaft I prefer tofprovide a longitudinal stay. bar 39, se-

cured at its end to the end frames and of ridged angle form, theridge presenting upwardly, and carrying the intermediate journal boxes 41, said stay bar being slotted at 42 for passage of the cranks and the ends of the crank legs in their rotation.

The pulley 17 is mounted at one end of a. lever 13, said lever being fulcrumed at 1 1- in a support 45 upon the main frame of the machine, and having a slot 16 engaged by a bolt 17 upon the handle end of the lever. To adjust the tension of the belt 15, the nut 48 upon said bolt is loosened, the lever moved to the necessary extent, the bolt work ing in the slot, and the nut being tightened to secure the adjustment.

I claim:

1. In a cotton gin, the combination with ginning rollers, breasts carrying ginning blades and a hacker frame having blades cooperating with the ginning blades, of means for operating said hacker frame comprising a cranked power shaft, a V-form frame having a lower transverse rod and upwardly extending diverging branches integral with said rod, said branches having each at its upper end an integral perforated lug, and a securing bolt engaging said perforation and securing said lug to the hacker blade, and a crank leg connecting said transverse rod with the crank of the power shaft. 2. In a cotton gin, end frames having vertical and horizontal flanges, a ginning roller, a breast provided with overlying end extensions and vertical bolt extensions engaging the slots of said horizontal flanges, a ginning blade carried by each breast and adapted to contact tangentially with said roller, upper and lower oppositely extending horizontal bolts having at their adjacent ends pivotal engagement with said end extensions, the lower of said bolts having at their outer ends engagement with the slots of said vertical flanges and nuts bearing against said flanges, turnbuckles connecting the approximated ends of said upper bolts, and coiled springs surrounding said vertical. bolts and bearing at their upper ends against said horizontal flanges and at their lower ends against said breast.

In testimony whereof I aiiix my signature, in presence of two witnesses.
